I would totally recommend Merlisa's place. It is certainly fantastic value. As a solo traveler, there was plenty of space. The pool was amazing, there are loads of conveniences nearby and central Bangkok is about 20 minutes away on the BTS which is conveniently located right outside.
If arriving by BTS then take exit 1 and Ideo Mix is the towers to the right. As I was arriving late, I took a taxi from the airport which was 350THB. I had some difficulty getting into the building initially as everything is keycard operated and Merlisa had left my keys inside the mailbox inside the lobby, but the security guards were friendly and let me in once I showed them my correspondence with Merlisa.
The apartment is lovely, perfect for one or two travelers. The 24hr market immediately below the building is perfect for stocking up on supplies, and there are dozens and dozens of food stalls on the main road selling everything from grilled meats to fresh juices. I recommend the pork skewers - delicious! - but be wary of grilled chicken from the street.
THE POOL IS FANTASTIC. I usually went for a swim for a couple of hrs each day, and up til about 4pm was often the only one there. The water is pristine, there is a small jacuzzi and also a small fitness center. You must bring a passport size photo to attach to the pass. I don't know if this is a new rule as it hadn't been mentioned in any previous reviews. I was caught out the first time I wanted to use the pool and was told I couldn't until I had a photo for the pass. Merlisa was quick to let me know where I could get some from which I appreciated, but come with one to save the aggro!
For me, this was everything I expected. A nice apartment with great facilities, just a quick and cheap ride from everything Bangkok has to offer. I would not hesitate to come back here next time I am in Bangkok. Thanks Merlisa!
